Abstract (en)
[origin: EP0699692A2] Aq. dispersions (I) contg. (A) at least partly grafted cellulose ether, and (B) a copolymer with a Tg of -40-0 degrees C. are obtd. by the copolymerisation of vinyl acetate and ethylene with vinyl esters of 3-18C aliphatic carboxylic acids or (meth)acrylate esters and/or maleic acid diesters of 1-18C aliphatic alcohols, in the presence of 0.05-0.95 wt.% alpha - beta -unsatd. carboxylic acid, 0-0.95 wt.% epoxy or OH gp.-contg. (meth)acrylate ester and 1.5-20 wt.% cellulose ether (w.r.t. total monomer content). Also claimed is the above process for the prepn. of (I). Pref. (I) contains (w.r.t. total monomer content in each case); (a) 1.7-15 wt.% (A), pref. hydrophobically modified hydroxyethyl-cellulose; (b) 50-70 wt.% vinyl acetate. 1.5-9 wt.% ethylene and more than 25 wt.% vinyl 3-12C aliphatic carboxylate, or (meth)acrylate or maleic acid diesters of 1-12C aliphatic alcohols, pref. 2-ethylhexyl acrylate or vinyl esters of 10-11C alpha -dimethyl-branched acids; and opt. (c) up to 10 wt.% water-soluble metal salts.
